Overview
The NLAS44599MN is a dual DPDT analog switch IC manufactured by onsemi, housed in a TSSOP-16 surface-mount package. It operates within a supply voltage range of 2 V to 5.5 V and supports four channels configured as two double-pole double-throw switches. Key electrical parameters include a maximum on-resistance of 25 Ohms, a maximum propagation delay of 14 ns, and a maximum off-time of 5 ns. The device functions reliably across an extended temperature range from -55°C to +125°C with a maximum power dissipation of 450 mW.
Feature Summary
- Dual DPDT configuration for flexible signal routing
- Low on-resistance for minimal signal attenuation
- Extended industrial temperature operation capability
Applications
- Signal multiplexing in data acquisition systems
- Audio and video signal path switching
- Test and measurement equipment signal routing
Procurement Notes
Verify component authenticity through authorized distribution channels due to discontinuation status. Confirm RoHS compliance documentation matches specific manufacturing lot requirements. Validate package integrity upon receipt to ensure solder joint reliability during assembly processes.
Selection Notes
Select this component when dual independent signal paths require low distortion switching within a compact footprint. Ensure the 25 Ohm on-resistance meets system impedance matching requirements. Verify that the 2 V to 5.5 V supply range aligns with available board power rails.
Part Context
This part belongs to the NLAS44599 series of high-speed analog switches. It shares functional similarities with other onsemi DPDT devices but offers specific pinout and performance characteristics tailored for space-constrained applications requiring robust signal isolation.
Replacement Considerations
Public confirmed substitute part numbers are not available. Consider evaluating equivalent DPDT analog switches from other manufacturers if sourcing becomes critical, ensuring parameter compatibility.
